User's Manual
Mediant 800B Gateway and E- SBC
Description
session effectively detects the Answer Tone
sent by a remote endpoint. This can be useful
when, for example, the payload of voice and
bypass is the same, allowing the originator to
switch to bypass mode as well.
Global parameter that enables Cisco's compatible
fax and modem bypass mode, Named Signaling
Event (NSE) packets. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_NSEMode). For a detailed description
of the parameter and for configuring this
functionality in the IP Profile table, see
''Configuring IP Profiles'' on page 396.
Note: If this functionality is configured for a
specific IP Profile, the settings of this global
parameter is ignored for calls associated with the
IP Profile.
Defines the NSE payload type for Cisco Bypass
compatible mode.
The valid range is 96-127. The default is 105.
Notes:

The parameter is applicable only to the
Gateway application.

Cisco gateways usually use NSE payload type
of 100.
Defines the port (with relation to RTP port) for
sending and receiving T.38 packets.

[0] = (Default) Use the RTP port +2 to
send/receive T.38 packets.

[1] = Use the same port as the RTP port to
send/receive T.38 packets.
Notes:

For the parameter to take effect, you must
reset the device.

When the device is configured to use V.152 to
negotiate audio and T.38 coders, the UDP
port published in SDP for RTP and for T38
must be different. Therefore, set the
T38UseRTPPort parameter to 0.
Defines the maximum size of a T.38 datagram
that the device can receive. This value is included
in the outgoing SDP when T.38 is used.
The valid range is 120 to 600. The default is 560.
Defines the maximum size (in bytes) of the
device's T.38 buffer. This value is included in the
outgoing SDP when T.38 is used for fax relay
over IP.
The valid range is 500 to 3000. The default is
3000.
Determines when the device initiates a T.38
